# options into their CLI. At the same time Puma doesn't provide an easy system
# of starting it *without* using the `Puma::CLI` class.
#
# To work around these problems we create our own parser and ignore any invalid
# option errors it throws up. This parser is used to handle options for the
# resource switcher.
